1.0 Background and Purpose The Centers for Disease Control and Prevention (CDC) established the Vessel Sanitation Program (VSP) in 1975 as a cooperative endeavor with the cruise vessel industry. VSP’s goal is to help the industry develop and implement comprehensive sanitation programs to protect the health of passengers and crew aboard cruise vessels.

Every cruise vessel that has a foreign itinerary, carries 13 or more passengers, and calls on a U.S. port is subject to biannual unannounced operational inspections and, when necessary, reinspection by VSP. The vessel owner pays a fee, based on gross registered tonnage (GRT) of the vessel, for all operational inspections. The Vessel Sanitation Program 2018 Operations Manual, which is available on the VSP website (www.cdc.gov/nceh/vsp), covers details of these inspections.

Additionally, cruise vessel owners or shipyards that build or renovate cruise vessels may voluntarily request plan reviews, onsite shipyard construction inspections, and/or final construction inspections of new or renovated vessels before their first or next operational inspection. The vessel owner or shipyard pays a fee, based on GRT of the vessel, for onsite and final construction inspections. VSP does not charge a fee for plan reviews or consultations.

Section 3.0 covers details pertaining to plan reviews, consultations, or construction inspections.

When a plan review or construction inspection is requested, VSP reviews current construction billing invoices of the shipyard or owner requesting the inspection. If this review identifies construction invoices unpaid for more than 90 days, no inspection will be scheduled. An inspection can be scheduled after the outstanding invoices are paid in full.

These guidelines were published in 1997 and 2001 as the Recommended Shipbuilding Construction Guidelines for Cruise Vessels Destined to Call on U.S. Ports. In 2005, the guidelines were renamed as the Vessel Sanitation Program 2005 Construction Guidelines. The guidelines were revised and published again as the Vessel Sanitation Program 2011 Construction Guidelines.

The VSP 2018 Construction Guidelines provide a framework of consistent construction and design guidelines that protect passenger and crew health. CDC is committed to promoting high construction standards to protect the public’s health. Compliance with these guidelines will help to ensure a healthy environment on cruise vessels.

CDC reviewed references from many sources to develop these guidelines. These references are indicated in section 38.2.

The VSP 2018 Construction Guidelines cover components of the vessel’s facilities related to public health, including FOOD STORAGE, PREPARATION, and SERVICE,

http://www.cdc.gov/nceh/vsp

and water bunkering, storage, DISINFECTION, and distribution. Vessel owners and operators may select the design and equipment that best meets their needs. However, the design and equipment must also meet the sanitary design criteria of the American National Standards Institute (ANSI) or equivalent organization as well as VSP’s routine operational inspection requirements.

These guidelines are not meant to limit the introduction of new designs, materials, or technology for shipbuilding. A shipbuilder, owner, manufacturer, or other interested party may ask VSP to periodically review or revise these guidelines in relation to new information or technology. VSP reviews such requests in accordance with the criteria described in section 2.0.

New cruise vessels must comply with all international code requirements (e.g., International Maritime Organization Conventions). Those include requirements of the following:

• Safety of Life-at-Sea Convention.• International Convention for the Prevention of Pollution from Ships.• Tonnage and Load Line Convention.• International Electrical Code.• International Plumbing Code.• International Standards Organization.

This document does not cross-reference related and sometimes overlapping standards that new cruise vessels must meet.

The VSP 2018 Construction Guidelines went into effect on June 1, 2018. • They apply to vessels that LAY KEEL or perform any major renovation or

equipment replacement (e.g., any changes to the structural elements of the vesselcovered by these guidelines) after this date.

• They apply to all areas of the vessel affected by a renovation.• They do not apply to minor renovations such as the installation or removal of

single pieces of equipment (refrigerator units, warewash machines, bain-marieunits, etc.) or single pipe runs.

VSP will inspect the entire vessel in accordance with the VSP 2018 Operations Manual during routine vessel sanitation inspections and reinspections.

2.0 Revisions and Changes VSP periodically reviews and revises these recommendations in coordination with industry representatives and other interested parties to stay abreast with industry innovations. A shipbuilder, owner, manufacturer, or other interested party may ask VSP to review a construction guideline on the basics of new technologies, concepts, or methods.

Recommendations for changes or additions to these guidelines must be submitted in writing to the VSP Chief (see section 39.2.1 for contact information). The


3

recommendation should • •

Identify the section to be revised. Describe the proposed change or addition.

• State the reason for recommending the change or addition. • Include research or test results and any other pertinent information that support

the change or addition. VSP will coordinate a professional evaluation and consult with industry to determine whether to include the recommendation in the next revision. VSP gives special consideration to shipyards and owners of vessels that have had plan reviews conducted before an effective date of a revision of these guidelines. This helps limit any burden placed on the shipyards and owners to make excessive changes to previously agreed-upon plans. VSP asks industry representatives and other knowledgeable parties to meet with VSP representatives periodically to review the guidelines and determine whether changes are necessary to keep up with the innovations in the industry. VSP will circulate proposed clarifications to the construction guidelines along with supporting information on their public health significance in advance of the annual meeting. These clarifications will be considered during the meeting. Proposed clarifications VSP considers time critical can be circulated to the industry and others for review and coordination through other collaborative means (e.g., email, web-based forum, etc.) for more timely dissemination and further review, as needed, during the annual meeting.

3.0 Procedures for Requesting Plan Reviews, Consultations, and Construction-Related Inspections

To coordinate or schedule a plan review or construction-related inspection, submit an official written request to the VSP Chief as early as possible in the planning, construction, or renovation process (see section 39.2.1 for contact information). Requests that require foreign travel must be received in writing at least 45 days before the intended visit. The request will be honored depending on VSP staff availability. After the initial contact, VSP assigns primary and secondary officers to coordinate with the vessel owner and shipyard. Normally two officers will be assigned. These officers are the points of contact for the vessel from the time the plan review and subsequent consultations take place through the final construction inspection. Vessel representatives should provide points of contact to represent the owners, shipyard, and key subcontractors. All parties will use these points of contact during consultations between any of the parties and VSP to ensure awareness of all consultative activities after the plan review is conducted.


4

3.1 Plan Reviews and Consultations VSP normally conducts plan reviews for new construction a minimum of 18 months before the vessel is scheduled for delivery. The time required for major renovations varies. To allow time for any necessary changes, VSP coordinates plan reviews for such projects well before the work begins. Plan reviews normally take 2 working days. They are conducted in Atlanta, Georgia; Fort Lauderdale, Florida; or other agreed-upon sites. Normally, two VSP officers will be assigned to the project. Representatives from the shipyard, vessel owner, and subcontractor(s) who will be doing most of the work should attend the review. They should bring all pertinent materials for areas covered in these guidelines, including (but not limited to) the following:

• Complete plans or drawings (this includes new vessels from a class built under a previous version of the VSP Construction Guidelines).

• Any available menus. • Equipment specifications. • General arrangement plans. • Decorative materials for FOOD AREAS and bars. • All FOOD-related STORAGE, PREPARATION, and SERVICE AREA plans. • Level and type of FOOD SERVICE (e.g., concept menus, staffing plans, etc.). • POTABLE and nonpotable water system plans with details on water inlets,

(e.g., sea chests, overboard discharge points, and BACKFLOW PREVENTION DEVICES).

• Ventilation system plans. • Plans for all RECREATIONAL WATER FACILITIES. • Size profiles for operational areas. • Owner-supplied and PORTABLE equipment specifications, including

cleaning procedures. • Cabin attendant work zones. • Operational schematics for misting systems and decorative fountains.

VSP will prepare a plan review report summarizing recommendations made during the plan review and will submit the report to the shipyard and owner representatives. Following the plan review, the shipyard will provide the following:

• Any redrawn plans. • Copies of any major change orders made after the plan review in areas

covered by these guidelines. While the vessel is being built, shipyard representatives, the ship owner, or other vessel representatives may direct questions or requests for consultative services to the VSP project officers. Direct these questions or requests in writing to the officer(s) assigned to the project. Include fax number(s) and an email address(es) for


5

appropriate contacts. The VSP officer(s) will coordinate the request with the owner and shipyard points of contact designated during the plan review.

3.2 Onsite Construction Inspections VSP conducts most onsite or shipyard construction inspections in shipyards outside the United States. A formal written request must be submitted to the VSP Chief at least 45 days before the inspection date so that VSP can process the required foreign travel orders for VSP officers (see section 3.0). Section 39.1 shows a sample request. A completed vessel profile sheet must also be submitted with the request for the onsite inspection (see section 40.0). VSP encourages shipyards to contact the VSP Chief and coordinate onsite construction inspections well before the 45-day minimum to better plan the actual inspection dates. If a shipyard requests an onsite construction inspection, VSP will advise the vessel owner of the inspection dates so that the owner’s representatives are present. An onsite construction inspection normally requires the expertise of one to three officers, depending on the size of the vessel and whether it is the first of a hull design class or a subsequent hull in a series of the same class of vessels. The inspection, including travel, generally takes 5 working days. The onsite inspection should be conducted approximately 4 to 5 weeks before delivery of the vessel when 90% of the areas of the vessel to be inspected are completed. VSP will provide a written report to the party that requested the inspection. After the inspection and before the ship’s arrival in the United States, the shipyard will submit to VSP a statement of corrective action outlining how it will address and correct each item identified in the inspection report.

3.3 Final Construction Inspections

3.3.1 Purpose and Scheduling At the request of a vessel owner or shipyard, VSP may conduct a final construction inspection. Final construction inspections are conducted only after construction is 100% complete and the ship is fully operational. These inspections are conducted to evaluate the findings of the previous yard inspection, assess all areas that were incomplete in the previous yard inspection, and evaluate performance tests on systems that could not be tested in the previous yard inspection. Such systems include the following:

• Ventilation for cooking, holding, and warewashing areas. • Warewash machines. • Artificial light levels. • Temperatures in cold- or hot-holding equipment. • HALOGEN and other chemistry measures for POTABLE WATER or • RECREATIONAL WATER systems.

To schedule the inspection, the vessel owner or shipyard submits a formal


6

written request to the VSP Chief as soon as possible after the vessel is completed, or a minimum of 10 days before its arrival in the United States. At the request of a vessel owner or shipyard and provided the vessel is not entering the U.S. market immediately, VSP may conduct final construction inspections outside the United States (see section 3.2 for foreign inspection procedures).

As soon as possible after the final construction inspection, the vessel owner or shipyard will submit a statement of corrective action to VSP. The statement outlines how the shipyard will address each item cited in the inspection report and includes the projected date of completion.

3.3.2 Unannounced Operational Inspection VSP generally schedules vessels that undergo final construction inspection in the United States for an unannounced operational inspection within 4 weeks of the vessel’s final construction inspection. VSP conducts operational inspections in accordance with the VSP 2018 Operations Manual.

If a final construction inspection is not requested, VSP generally will conduct an unannounced operational inspection within 4 weeks after the vessel’s arrival in the United States. VSP conducts operational inspections in accordance with the VSP 2018 Operations Manual.

4.0 Equipment Standards, Testing, and Certification Although these guidelines establish certain standards for equipment and materials installed on cruise vessels, VSP does not test, certify, or otherwise endorse or approve any equipment or materials used by the cruise industry. Instead, VSP recognizes certification from independent testing laboratories such as NSF International, Underwriter’s Laboratories (UL), the American National Standards Institute (ANSI), and other recognized independent international testing institutions.

In most cases, independent testing laboratories test equipment and materials to certain minimum standards that generally meet the recommended standards established by these guidelines.

Equipment built to questionable standards will be reviewed by a committee from VSP, cruise ship industry, and independent testing organizations. The committee will determine whether the equipment meets the recommended standards established in these guidelines. Copies of test or certification standards are available from the independent testing laboratories.

Equipment manufacturers and suppliers should not contact the VSP to request approval of their products.

6.0 General Facilities Requirements

6.1 Size and Flow Many factors determine and influence the size of rooms and work areas and the flow of FOOD through a vessel. Those factors can include the vessel size, number of passengers and crew, types of FOODS and menus, number of meals and mealtimes, service or presentation of meals, itinerary, and vessel owner’s experience. In general, FOOD STORAGE, PREPARATION, SERVICE and TRANSPORTATION areas; warewashing areas; and waste management areas must be sized to accommodate the vessel’s full capacity of passengers and crew. Bulk FOOD STORAGE AREAS or provision rooms (e.g., frozen stores, refrigerated stores, and DRY STORAGE AREAS) must be sized to prevent the storage of bulk FOODS in provisions passageways unless the passageways are specifically designed to meet provision room standards (section 15.0). Refrigeration and hot-FOOD holding facilities, including temporary storage facilities, must be available for all FOOD PREPARATION and SERVICE areas and for FOODS being transported to remote areas.

6.1.1 Food Flow Arrange the flow of FOOD through a vessel in a logical sequence that eliminates or minimizes cross-traffic or backtracking. Provide a clear separation of clean and soiled operations. When a common corridor is used for movement of both clean and soiled operations, the minimum distance from BULKHEAD to BULKHEAD must be considered. Within a galley, the standard separation between clean and soiled operations must be a minimum of 2 meters (6½ feet). For smaller galleys (e.g., specialty, bell box) the minimum distance will be assessed during the plan review. Additionally, common corridors for size and flow of galley operations will be reviewed during the plan review. Provide an orderly flow of FOOD from the suppliers at dockside through the FOOD STORAGE, PREPARATION, and finishing areas to the SERVICE areas and, finally, to the waste management area. The goals are to reduce the risk for cross-contamination, prepare and serve FOOD rapidly in accordance with strict time and temperature-control requirements, and minimize handling. Provide a size profile for each FOOD AREA, including provisions, preparation rooms, galleys, pantries, warewash, garbage processing area, and storage. The size profile shows the square meters of space designated for that area. Where possible, VSP will visit the profile vessel(s) to verify the capacity during operational inspections. The size profile must be an established standard for each cruise line based on the line’s review of the area size for the same FOOD AREA in its existing vessels. As the ship size and passenger and crew totals change, there must be a proportional change in each FOOD AREA size based


20

on the profile to ensure the service needs are met for each area. Size evaluations of FOOD AREAS will incorporate seating capacity and staffing, service, and equipment needs. During the plan review process VSP evaluates the size of a particular room or area and the flow of FOOD through the vessel to those rooms or areas. VSP will also use the results of operational inspections to review the size profiles submitted by individual cruise lines.

6.2 Equipment Requirements

6.2.1 Galleys The equipment in sections 6.2.1.1 through 6.2.1.12 is required in galleys depending on the level and type of service. This equipment may be recommended for other areas.

Electronic data loggers with CERTIFIED DATA SECURITY FEATURES may be installed in lieu of chart recorders. Acceptable data loggers produce records that conform to the principles of operation and data display required of the analog charts, including printing the records. Use electronic data loggers that log times in increments of


78

<15 minutes. Written documentation from the data logger manufacturer, such as a letter or instruction manual, must be provided to verify that the features are secure.

22.14.2.9 Multiple Distribution Loops When supplying POTABLE WATER throughout the distribution network with more than one ring or loop (lower to upper decks or forward to aft), there must be

• Pipe connections that link those loops and a single distant point monitoring analyzer or

•

Individual analyzers on each ring or loop.

A single return line that connects to only one ring or loop of a multiple loop system is not acceptable. One chart recorder may be used to record multiple loop readings. POTABLE WATER distribution loops/rings supplied by separate HALOGEN dosing equipment must include an analyzer chart recorder at a distant point for each loop/ring.

25.0 Recreational Water Facilities Water Source

25.1 Filling System Provide a filling system that allows for the filling of each RECREATIONAL WATER FACILITY with SANITARY SEAWATER or POTABLE WATER. For a compensation or make-up tank supplied with POTABLE water, an overflow line located below the fill line and at least twice the diameter of the fill line is an acceptable method of BACKFLOW protection as long as the overflow line discharges to the wastewater system through an indirect connection. If make-up water is introduced into the RECREATIONAL WATER FACILITY directly, the water should be at the same level of HALOGENATION and PH as the RWF before entering the RECREATIONAL WATER FACILITY. Avoid BLIND LINES in the water systems of recreational water facilities.

25.2 Compensation or Make-Up Tank Where make-up water is required to replace water loss due to splashing, carry out, and other volume loss, install an appropriately designed compensation or make-up tank to ensure that ADEQUATE chemical balance can be maintained.

25.3 Combining Recreational Water Facilities No more than two similar RECREATIONAL WATER FACILITIES may be combined. CHILDREN’S POOLS and BABY-ONLY WATER FACILITIES must not be combined with any other type of RWFs.

25.4 Independent Manual Testing When combining RECREATIONAL WATER FACILITIES, provisions must be made for independent manual water testing within the mechanical room for each RECREATIONAL WATER FACILITY.

25.5 Independent Slide Recreational Water Facility and Adult Swimming Pool An independent slide RECREATIONAL WATER FACILITY and an adult SWIMMING POOL may be combined provided that the water volume added to the slide and the slide pump capacity are sufficient to maintain the TURNOVER rate as shown in section 29.10. Any other combinations of RECREATIONAL WATER FACILITIES will be decided on a case-by-case basis during the plan review.


83

26.0 Recreational Water Facility Showers and Toilet Facilities

26.1 Shower Temperature Equip showers to provide POTABLE WATER at a temperature not to exceed 43°C (110°F) during normal operations.

26.2 Shower Location Install showers within 10 meters (33 feet) of every entry point to each RECREATIONAL WATER FACILITY. For beach entry RECREATIONAL WATER FACILITIES, install a minimum of one showerhead per 10 meters (33 feet) of perimeter within 10 meters (33 feet) of the beach perimeter. Install a minimum of one shower at each waterslide staircase entrance. The location and number of showers for facilities with multiple entrances will be determined during the plan review.

26.3 Showers for Children RECREATIONAL WATER FACILITIES designed for use by children under 6 years of age must have appropriately sized shower facilities. Standard height is acceptable, but the mechanism to operate the flow of water must not be more than 1 meter (3 feet) above the deck.

26.4 Showers Drainage Shower floors must be sloped to drain. Shower water must discharge to waste, and not into the RECREATIONAL WATER FACILITY.

26.5 Toilet Facilities Locate toilet facilities within one fire zone (approximately 48 meters [157 feet]) of each RECREATIONAL WATER FACILITY and on the same deck or adjacent decks if there is no obstruction between the RECREATIONAL WATER FACILITY area and entrances to the toilets. If toilets are not located on the same deck as the RECREATIONAL WATER FACILITY, they should be easily visible and ACCESSIBLE from the RECREATIONAL WATER FACILITY area. Install a minimum of two separate toilet rooms (either two unisex or one male and one female). Each toilet facility must include a toilet and a handwashing facility. The total number of toilets and toilet facilities required will be assessed during the plan review. Urinals may be installed in addition to the required toilet, but may not replace the toilet.

26.6 Waterslide Toilets and Showers Toilet facilities for a waterslide may be located on the same deck within one fire zone (approximately 48 meters [157 feet]) as the staircase entrance as long as this is the only access to the waterslide.


84

Showers for a waterslide may be located within 10 meters (33 feet) of the staircase entrance as long as this is the only access to the waterslide.

26.7 Diaper-Changing Facilities Provide diaper-changing facilities within one fire zone (approximately 48 meters [157 feet]) and on the same deck of any BABY-ONLY WATER FACILITY. If these facilities are placed within toilet rooms, there must be one facility located within each toilet room (men’s, women’s, and unisex). Diaper-changing facilities must be equipped in accordance with section 34.2.1.

27.0 Recreational Water Facility Drainage

27.1 Independent System Provide an independent drainage system for RECREATIONAL WATER FACILITIES from other drainage systems. If RECREATIONAL WATER FACILITY drains are connected to another drainage system, provide an AIR GAP or a DUAL SWING CHECK VALVE between the two. This includes the drainage for compensation or make-up tanks.

27.2 Slope Slope the bottom of the RECREATIONAL WATER FACILITY toward the drains to achieve complete drainage.

27.3 Seating Drains If seating is provided inside a RECREATIONAL WATER FACILITY, ensure drains are installed to allow for complete draining of the seating area (including seats inside WHIRLPOOL SPAS and SPA POOLS).

27.4 Drain Completely Decorative and working features of a RECREATIONAL WATER FACILITY must be designed to drain completely and must be constructed of nonporous EASILY CLEANABLE materials. These features must be designed to be shock HALOGENATED.

28.0 Recreational Water Facility Safety

28.1 Antientrapment Drain Covers and Suction Fittings Where referenced within these guidelines, drain covers must comply with the requirements in ASME A112.19.8-2007, including addenda. See table below for primary and secondary ANTIENTRAPMENT requirements. VSP is aware that the requirements shown in Table 28.1.7 may not fully meet the letter of the Virginia Graeme Baker Act, but we also recognize the life-safety concerns for rapid dumping of RECREATIONAL WATER FACILITIES in conditions of instability at sea. Therefore, it is the owner’s decision to meet or exceed VSP requirements.


85

28.1.1 Installation Install dual drains at least 1 meter (3 feet) apart and at the lowest point in the RECREATIONAL WATER FACILITY. Ensure that there are no intermediate drain isolation valves on the lines between the drains (Figure 19a). In a channel system (an UNBLOCKABLE DRAIN), a grate-type cover would be attached to the channel (Figure 19b).

28.1.2 ASME A112.19.8M-2007 When fully assembled and installed, SUCTION FITTINGS must prevent the potential for body, digit, or limb entrapment in accordance with ASME A112.19.8M-2007.

28.1.3 Stamped and Certified Manufactured drain covers and SUCTION FITTINGS must be stamped and certified in accordance with the standards set forth in ASME A112.19.8-2007.

28.1.4 Design of Field Fabricated Covers and Fittings The design of custom/shipyard constructed (field fabricated) drain covers and SUCTION FITTINGS must be fully specified by a registered design professional in accordance with ASME A112.19.8-2007.

*Options 1 through 5 are for fittings not under direct suction. These include both fittings to drain the RECREATIONAL WATER FACILITY and fittings used to recirculate the water. Options 6 through 8 are for fittings under direct suction. These include fittings to drain the RECREATIONAL WATER FACILITY and fittings to recirculate the water. **Definitions:

• Alarm = the audible alarm must sound in a continuously manned space AND at the RECREATIONAL WATER FACILITY. This alarm is for all draining: accidental, routine, and emergency.

• GDS (GRAVITY DRAINAGE SYSTEM) = a drainage system that uses a collector tank from which the pump draws water. Water moves from the RECREATIONAL WATER FACILITY to the collector tank due to atmospheric pressure, gravity, and the displacement of water by bathers. There is no direct suction at the RECREATIONAL WATER FACILITY.

• SVRS (SAFETY VACUUM RELEASE SYSTEM) = a system that stops pump operation, reverses circulation flow, or otherwise provides a vacuum release at a suction outlet when a blockage is detected. The system must be tested by an independent third party and conform with ASME/ANSI A112.19.17 or ASTM standard F2387.

• APS (AUTOMATIC PUMP SHUT-OFF system) = a device that detects a blockage and shuts off the pump system. A manual shut-off near the RECREATIONAL WATER FACILITY does not qualify as an APS.

28.2 Depth Markers

28.2.1 Installation Install depth markers for each RECREATIONAL WATER FACILITY where the maximum water depth is 1 meter (3 feet) or greater. Install depth markers so they can be seen from the deck and inside the RECREATIONAL WATER FACILITY tub. Ensure the markers are in both meters and feet. Additionally, depth markers must be installed for every 1-meter (3-foot) change in depth.

28.3 Safety Signs

28.3.1 Installation Install safety signs at each RECREATIONAL WATER FACILITY except for BABY-ONLY WATER FACILITIES. At a minimum the signs must include the following words:

• Do not use these facilities if you are experiencing diarrhea, vomiting, or fever.

• No children in diapers or who are not toilet trained. • Shower before entering the facility. • Bather load number. (The maximum bather load must be based on the


88

following factor: One person per 19 liters [5 gallons] per minute of recirculation flow.)

Pictograms may replace words, as appropriate or available. It is advisable to post additional cautions and concerns on signs. See section 31.3 for safety signs specific to BABY-ONLY WATER FACILITIES and section 32.1.3 for safety signs specific to WHIRLPOOL SPAS and SPA POOLS.

28.3.1.1 Children’s Recreational Water Facility For signs in children’s RECREATIONAL WATER FACILITIES, include the exact wording “TAKE CHILDREN ON FREQUENT BATHROOM BREAKS” or “TAKE CHILDREN ON FREQUENT TOILET BREAKS.” This is in addition to the basic RECREATIONAL WATER FACILITY safety sign.

28.4 Life-Saving Equipment

28.4.1 Location A rescue or shepherd’s hook and an APPROVED floatation device must be provided at a prominent location (visible from the full perimeter of the pool) at each RECREATIONAL WATER FACILITY that has a depth of 1 meter (3 feet) or greater. These devices must be mounted in a manner that allows for easy access during an emergency.

• The pole of the shepherd’s hook must be long enough to reach the center of the deepest portion of the pool from the side plus 0.6 meters (2 feet). It must be light, strong, and nontelescoping with rounded nonsharp ends.

• The flotation device must have an attached rope that is at least two-thirds of the maximum pool width.

29.0 Recirculation and Filtration Systems

29.1 Skim Gutters Where skim gutters are installed, ensure that the maximum fill level of the RECREATIONAL WATER FACILITY is to the skim gutter level.

29.2 Overflows Ensure that overflows are directed by gravity to the compensation or make-up tank for filtration and DISINFECTION. Alternatively, overflows may be directed to the RECREATIONAL WATER FACILITY drainage system. If the overflow is connected to another drainage system, provide an AIR GAP or a DUAL SWING CHECK VALVE between the two.


89

29.3 Return Water All water returning from a RECREATIONAL WATER FACILITY must be directed to the compensation or make-up tank or the filtration and DISINFECTION system.

29.4 Compensation or Make-Up Tanks Ensure that 100% of the water in the compensation or make-up tanks passes through the filtration and DISINFECTION systems before returning to the RECREATIONAL WATER FACILITY. This includes any water directed to water features in RECREATIONAL WATER FACILITIES.

29.5 Approved Install recirculation, filtration, and DISINFECTION equipment that has been APPROVED for use in RECREATIONAL WATER FACILITIES based on NSF International or an equivalent standard.

29.6 Centrifugal Pumps Ensure that pumps used to recirculate RECREATIONAL WATER FACILITY water are centrifugal pumps that they are self-priming or prime automatically. Flooded end suction pumps are permitted if suitable for the application.

29.7 Skimmers or Gutters Install surface skimmers or gutters capable of handling 100% of the filter flow of the recirculation system. If skimmers are used instead of gutters, install at least one skimmer for every 37 square meters (400 square feet) of pool surface area.

29.8 Hair and Lint Strainer Provide a hair and lint strainer between the RECREATIONAL WATER FACILITY outlet and the suction side of the pumps to remove foreign debris such as hair, lint, hair pins, bandages, etc. Ensure the REMOVABLE portion of the hair and lint strainer is corrosion resistant and has holes no greater than 6 millimeters (1/4 inch) in diameter.

29.1 Filters

29.1.1 Particle Size Use filters designed to remove all particles greater than 20 microns from the entire volume of the RECREATIONAL WATER FACILITY within the specified TURNOVER rate.

29.1.2 Cartridge or Media Type Use cartridge or media-type filters (e.g., rapid-pressure sand filters, high rate sand filters, diatomaceous earth filters, gravity sand filters). Make filter sizing consistent with American National Standards Institute (ANSI) standards for


90

public RECREATIONAL WATER FACILITIES. Ensure commercial filtration rates for calculations are used for cartridge filters if multiple rates are provided by the manufacturer.

29.9.3 Backwash Ensure media-type filters are capable of being backwashed. Provide a clear sight glass on the backwash side of all media filters.

29.9.4 Accessories Install filter accessories, such as pressure gauges, air-relief valves, and flow meters. Install safety features on delivery lines to control chemical dosing unless the design of the system prevents water flow to analyzers if circulation fails.

29.9.5 Access Design and install filters and filter housings in a manner that allows access for inspection, cleaning, and maintenance.

29.9.6 Manufacturer’s Information Provide manufacturer’s specifications and recommendations for filtration systems.

29.10 Turnover Rates Install recirculation pumps, filtration, and DISINFECTION equipment that have the capacity to turn over water in the RECREATIONAL WATER FACILITY at the appropriate rates as set forth in table the below. Ensure that TURNOVER rates may be increased based on bather load. (The maximum bather load must be based on the following factor: One person per 19 liters [5 gallons] per minute of recirculation flow.) RECREATIONAL WATER FACILITY TURNOVER Rate SWIMMING POOL 4 hours CHILDREN’S POOL 0.5 hours WADING POOL 1 hour WHIRLPOOL SPA 0.5 hours SPA POOL 2 hours INTERACTIVE RECREATIONAL WATER FACILITY or ACTIVITY POOL (< 610 millimeters [24 inches] deep)

1 hour

INTERACTIVE RECREATIONAL WATER FACILITY or ACTIVITY POOL (> 610 millimeters [24 inches] deep)

2 hours

BABY-ONLY WATER FACILITY 0.5 hours Custom installations (where the above is not applicable)

To be determined by design engineer with VSP review


91

For a RECREATIONAL WATER FACILITY in sea-to-sea mode, ensure a TURNOVER rate of once per hour. For facilities that meet the definition of more than one type of RECREATIONAL WATER FACILITY, the more protective turnover rate applies. For example, if a CHILDREN’S POOL also has features of an INTERACTIVE RECREATIONAL WATER FACILITY or ACTIVITY POOL, the TURNOVER rate must be 0.5 hours.

29.11 Primary Disinfection and pH Control

29.11.1 Installation Install independent automatic analyzer-controlled HALOGEN-based DISINFECTION and PH dosing systems for each RECREATIONAL WATER FACILITY or combined RECREATIONAL WATER FACILITIES as allowed in sections 25.3 and 25.6. The analyzer must be capable of measuring HALOGEN levels in MG/L (ppm) and PH levels. Analyzers must have digital readouts that indicate measurements from the installed analyzer probes.

29.11.2 Monitoring and Recording Provide an automatic monitoring and recording system for the free HALOGEN residuals in MG/L (ppm) and PH levels. The recording system must be capable of recording these levels 24 hours/day. Install chart recorders or electronic data loggers with CERTIFIED DATA SECURITY FEATURES that record PH and HALOGEN measurements. If POTABLE WATER is introduced into RECREATIONAL WATER FACILITIES with recirculated water after filtration and chemistry control and the POTABLE WATER combines with the RECREATIONAL WATER FACILITY recirculation system, the POTABLE WATER must be HALOGENATED and PH controlled to the level required for the RECREATIONAL WATER FACILITY. The resulting mixture would negatively impact the monitoring analyzer for the RECREATIONAL WATER FACILITY. Electronic data loggers must be capable of recording in increments of ≤15 minutes. Written documentation from the data logger manufacturer, such as a letter or instruction manual, must be provided to verify that the features are secure. The probe for the automated analyzer recorder must be installed before the compensation or make-up tank or from a line taken directly from the RECREATIONAL WATER FACILITY. Install appropriate sample taps for analyzer calibration.


92

29.11.3 Analyzer Probes For WHIRLPOOL SPAS and SPA POOLS, analyzer probes for the dosing and recording system must be capable of measuring and recording levels up to 10 MG/L (10 ppm).

29.11.4 Alarm Provide an audible alarm in a continuously occupied watch station (e.g., the engine control room) to indicate low and high free HALOGEN and PH readings in each RECREATIONAL WATER FACILITY.
